Matter cycles. Matter for growth, maintenance and reproduction in all organisms cycles through the ecosystem and Earth processes. All life needs certain matter in order to stay alive. This includes nitrogen, phosphorus, and water; oxygen for many but not all animals; and carbon dioxide for plants, to name a few kinds of matter.

To understand, through guided visualization (part 1) and hands-on investigations (part 2), how matter cycles through an ecosystem. To gain an understanding of decomposition, a community of forest recyclers, and the critical role decomposers play in the food web and the cycling of matter.

Students investigate biodiversity of wildlife in their backyard (schoolyard) by selecting and mapping out areas they expect to be high in biodiversity in part one. Part two uses a larger area to make observations about the area by using “biodiversity clues.”

This text is illustrated with updated graphs, photos and cites the work of hundreds of scientists and organizations such as the IPCC, NASA, Environment Canada, Royal Society of Canada, and Natural Resources Canada, to name a few. My resource is an update on the science of climate change, extreme weather, protecting nature and biodiversity, advancing renewable energy, and reducing greenhouse gas emissions with frequent reference to Canada and in particular British Columbia. Global impacts, mitigation and adaptation are explained throughout the text.
My ten years of research cites reputable journals, national and international organizations and the media. Research covers climate change from the Arctic to the Antarctic, projection of climate change, how to reduce greenhouse gas emissions, El Nino/La Nina, extreme weather, renewables, the oil sands and transport of bitumen, and Canada's contribution at the UN COP meetings. This book is meant as a resource for our youths to make wise decisions about their future.

"Decomposition Mission" by Beetles Science and Teaching for Field Instrctors

In this activity, students investigate the fascinating and complex process of decomposition and lay the foundation for deeper understanding of concepts related to matter and energy transfer in ecosystems. Through exploration and discussion, students go beyond simple definitions. Instead, students discover key characteristics of decomposition as they struggle with creating a sequence for decomposing wood and leaves. They learn the difference between physical decomposition and chemical decomposition and that many things contribute to decomposition, but certain organisms are classified as decomposers. They also search for and discuss evidence of decomposers, make model diagrams to further develop their ideas about the process of decomposition, and discuss decomposition and its role in the cycling of matter. Finally, students are challenged to recognize the evidence and impact of decomposition in the ecosystems they explore.

Students will:
- Explore, observe, and compare samples of decomposing materials and use reasoning to determine the level of decomposition among them
- Search for and classify decomposers (or evidence of them) as fungi, bacteria or invertebrates
- Investigate and discuss decomposition as the process of breaking down dead organisms and their waste materials into smaller and simpler forms of matter
- Create a model diagram for the process of decomposition
- Discuss the role decomposers play in making matter available to living plants

Students explore a forest at designated stations, using their vision and, blindfolded, their other senses. By engaging with the forest in a personal, multisensory activity, students will become more sensitive to the components of a forest, and hopefully, treat our landscapes with increased respect.

Students use forest stores from their ecoprovince to examine and define the elements of food chains and food webs including abiotic and biotic interactions. Students as ‘food chain roles’ participate in an string webbing activity that demonstrates how roles are inter-connected and the resilience of food webs to adapt to stresses.
